System Traps

A system trap (also called a system alarm) is where a trap/alarm has been triggered because the

number of warnings has exceeded the defined threshold. The trap is defined in the Trap

Threshold Settings dialog box.

A trap can be defined for the total number of warnings detected on the system, or the total

number of warnings detected on an individual terminal. Each trap has a specified interval during

which the number of warnings must be accumulated.

The RTCP Monitor periodically checks to see if the defined interval has expired. It counts the

number of warnings recorded during this interval. If it has reached the defined threshold, a

system alarm is generated. To generate an alarm as soon as the thresholds are reached, use an

interval of zero (0).

The system alarm can be based on any combination of jitter, delay (RTT), or packet loss.

Example

This example shows values entered in the Trap Threshold Settings dialog box. These values

would result in a warning being logged at the end of the call, if at any time during the call the jitter

>=45, or the %loss >= 4. If the number of warnings logged in any 24-hour period exceeds 100, as

defined in the System’s No# of Warnings column, a system trap is sent.
